PROBLEM TO BE SOLVED: To provide a cross shaft joint 5 (6) capable of achieving action stability of a roller bearing 11 and easiness to incorporation of it. SOLUTION: In the roller bearing 11 installed to four trunnions 10a-10d in a cross shaft 10, oil-containing polymer 20 is filled and solidified in a gap between a circumscribed circle and an inscribed circle of each of a plurality of rollers 16 in the inner circumference of an outer ring cup 15. The oil-containing polymer 20 exudes oil to transfer to be fed to the rollers 16, etc. Since the oil-containing polymer 20 is solid, deterioration is hard to occur by penetration of water unlike grease that has fluidity.
